I noticed something strange in SharePoint Online and would like to get your confirmation for this behaviour or your comment if I am doing anything wrong.
We have many guest users in our organisation and some of them need access to SharePoint. This access can be given if I add those users in the library settings explicitly:
- The site has guest sharing enabled - The guests are already added in our AD (existing guest users) - The library has unique permissions
This works as expected and guests can access.
But if I add those guest users to an AAD security group (not a SharePoint group) and add the group in this list, they always get this screen here:
This is an issue, because we are using security groups in many libraries and adding users manually is a huge pain... do you have any suggestions? Are guest users from security groups not synced in the corresponding SharePoint groups?
